MlTER-BOX.

SPECIFICATION forming part of Letters Patent No. 401,423, dated April16, 1889. Application filed October 10, 1888 Serial No. 287,754. (Nomodel.)

To all whom it may concern:

Be it known that I, TILLIAM H. ENGLE- HARD, a citizen of the UnitedStates, residing at Espy, in the county of Columbia and State ofPennsylvania, have invented new and useful Improvements in Miter-Boxes,of which the following is a specification.

My invention relates to improvements in miter-boxes; and it consists ina certain novel construction and combination of devices fully set forthhereinafter in connection with the accompanying drawings, andspecifically pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a miter-box embodyingmy improvements. Fig.2 is a bottom plan view thereof. Fig. 3 is atransverse central sectional view of the same. Fig. l is a perspectiveview of the miter-box having the bevel-plates adjusted thereon. Fig. 5is a transverse sectional view on the line a: m of Fig. Fig. 6 is a planview of a portion of the device to illustrate the manner of connectingthe guides to the lever. Fig. 7 is a detail view of the cam-lever.

Referring by letter to the drawings, A designates the angle-box,comprising the base a and the vertical side a, which is provided at itscenter with a vertical opening, a and B B designate suitable standardsor legs which are secured to the under side of the base to support thesame a short distance above the bench or table upon which the devicestands.

On an ear, 0, which projects a short distance beyond the rear side ofthe box, is pivoted the adjusting-lever G, and the free end of the leverbears on a semicircular guide, D, which is arranged slightly below thelower side of the base a. This guide is attached at its ends to acasting, E, which is aiiixed to the under side of the base a, and theear 0 also forms a part of the said casting.

The guide D is provided with a longitudinal slot, cl, in which theadjusting-bolts F F are arranged, for a purpose to be hereinafterexplained, and D represents a strengthening or stifiening rib at theinner edge of the guide.

G G represent arched sawguides having lateral strengthening orstiffening ribs 9 g, and provided at their rear ends with the horizontalextensions G G. These extensions are provided on their lower sides withtransverse ribs g g, which fit in a transverse groove, 9 in the heel ofthe lever, and h h represent apertures in the said extensions whichalign with transverse slots h in the heel of the lever. Bolts H H engagethe said slots an d apertures and secure the rear ends of the jaws atany desired distance apart to suit the set of the saw which is to bepassed between them.

The saw-guidescurve forward and over the front side of the base, and totheir extremities is aflixed the clamp 1, consisting of the verticalarms K K, provided with longitudinal slots 76 k, which are engaged byset-screws k k on the guides. The upper ends of the said arms areconnected by the adj ustingbolt L,which passes transverselyt-herethrough, and the set-screws M M, which are arranged, respectively,above and below the adjustingbolt, pass through threaded apertures m min one of the arms and bear at their ends against the other arm.

To open or close the saw-guides, loosen or tighten the adj usting-boltand arrange the setscrews to bear firmly against the side of the arm,thereby locking the arms against further movement. The slots in the armsK enable the latter to be adjusted vertically to allow any desiredinclination of the saw, and the arms are clamped in the desired positionby tightening the set-screws k it.

It will be understood from the foregoing description that to arrange thesaw-guides at any desired angle it is only necessary toswing the freeend of the adjustingdever toward one end of the box or the other, and tolock the lever in this position I provide it at its free end on theunder side with the cam-lever N. This cam-lever bears against the outeredge of the guide D, and is provided with a horizontal lip, a, whichextends under the guide when the latter is in its operative position andholds the adj listing-lever firmly against its upper side. When it isdesired to make a square cut, the lever is arranged at the center of theslotted guide, and the adjustingbolts F F are placed on opposite sidesthereof and tightened, thereby guarding against accidental displacement.A false bottom, 0, is affixed on the upper side of the base a to receive the cuts, which are unavoidable in the use of a miter-box, and itis provided near its ends with the transverse slots P P, havingenlargements p p at their front ends.

Q Q designate bevel-plates, having apertures q g at their lower edges,which register with the slots in the false bottom, and R R representadjusting-bolts, which pass through the said apertures and engage theslots in the bottom to enable the said plates to be arranged in thedesired position. The inner ends of the said plates are beveled and mitered, and the said ends are designed to be aligned with the opening ain the side of the box.

The molding or strip to be matched or mitered is placed against .theplate in the ordinary way, as will be understood.

Having described my invention, I claim- 1. The combination, with themiter-box, of the lever mounted thereon and provided with suitablelooking devices, the arched sawguides'affixed at their rear ends to theheel of the lever, and the clamp comprising the arms aflixed to thefront ends of the said guides and connected by an adjusting-bolt, L,whereby the extremities of the guides may be relatively adjusted,substantially as specified.

2. The combination, with the miter-box, of the lever mounted thereon andprovided with suitable locking devices, the arched sawguides afiixed tothe heel of the lever and provided at their extremities with thesetscrews It It, the vertical slotted arms K K, mounted on the saidset-screws, the adj 11sting-bolt L, connecting the upper ends of thearms, and the set-screws M M, engaging transverse apertures in the upperend of one of the arms and bearing against the other arm, substantiallyas specified.

3. The combination, with the miter-box, of the lever mounted thereon andprovided with suitable locking devices, the arched sawguides provided attheir rear ends with apertures h h, which register with transverse slotsin the heel of the said lever, the adjustingbolts H H, engaging theapertures and the slot, and the clamp I, connecting the free extremitiesofthe guides, substantially as specified.

4. The combination, with the miter-box, of the lever mounted thereon andprovided at its heel with the transverse groove 9 and the transverseslot h, the saw-guides provided at their rear ends with the ribs g g,fitting in the groove g and the apertures h h, registering with the sloth, the adjusting-bolts H H, engaging the registering slot and apertures,and the clamp connecting the free ends of the said guides and comprisingthe arms K K, atfixed, respectively, to the guides and connected by anadjusting-bolt, L, whereby they are relatively adjustable, substantiallyas specified.

5. The combination, with the miter-box, of the semicircular guidearranged under the base-plate thereof, the lever C, mounted onthe boxand bearing at its free end on the said guide, the cam-lever mounted onthe said lever and provided with a lip, 12, engaging under thesemicircular guide, and the arched saw-guides affixed to the heel of thelever C, substantially as specified.

6. The combination, with the miter-box, of the semicircular slottedguide D, the lever O, mounted on the box and provided with the archedsawguides G G, the cam-lever N, mounted on the lever G and adapted toengage the guide D, and the adjusting-bolts F F, arranged in the slot ofthe guide D and adapted to be adjusted on opposite sides of the lever O,substantially as and for the purpose specified. 1

. 7. The combination, with the miter-box having its bottom provided withtransverse slots P P, and the lever C, mounted on the box and providedwith the saw-guides G, of the bevelplates Q Q, provided at their loweredges with apertures q q, adapted to register with the slots P P, andthe adjustingbolts R R, en-' gaging the registering apertures and slotsto clamp the said plates in the desired position, substantially as andfor the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM H. ENGLEHARD.
